Product Description:
Take the stress and procrastination out of picture hanging! The push and hang picture hanging tool from HANGMAN products is the only tool that allows you to put 2 nails into the wall at the same time! The nails install at the correct angle and depth to hold your picture securely, and align precisely with D-rings, triangle, Sawtooth or other fixtures on the back of your picture. Push-and-hang comes with 50 standard #17 nails, which can be replenished at any hardware store. Magnetic holders keep your nails in place, eliminating lost or dropped nails, until you are ready to install. Just slip in the nails, then use 1 “punch-like” motion and you’re done. It’s that simple!
